Sorry to see you here. Being oestrogen and progesterone positive means that these hormones are feeding your tumour. You mentioned that your tumour is grade 1 which means it’s slow growing (grade 3 means aggressive and fast growing and grade 2 is in between), invasive but no lymph node involvement means that it’s in the boob only. You will most likely have more tests done which will be ordered by BS to ensure no nasties anywhere else and to guide what type of treatment needed.
To give you an idea....
I was 40 when diagnosed (2018), hormone positive (oestrogen and progesterone) but HER2 negative. Tumour was 2.2cm, invasive, grade 3 and I had multicentric involvement (microcalcifications which had cancer) plus lymph node involvement. I had aggressive treatment with chemo and radiotherapy, then bilateral mastectomy with axillary clearance and now on hormone therapy. I am currently NED (no evidence of disease).
My mother has just recently been diagnosed. Hormone positive, HER2 negative, invasive grade1-2 no lymph node involvement tumour is under 2cm. Treatment is lumpectomy, radiotherapy and hormone therapy. Of course this may change when they get results of senitial node biopsy (which is done at time of surgery to see if any lymph node involvement) - but ultrasound and MRI both show no lymph node involvement.
Good luck. This online network is very supportive.
